I'm building with target_os=chromeos and trying to debug issues with touch events on multiple displays.

For faster development I'm trying to do some debugging on my host, like this:

> chrome --touch-devices=9 --ash-host-window-bounds="801+0-800x800,0+0-800x800"

No matter which display I click in, the simulated touch event appears on the first display. I'm unable to send touch events to the second display.

When I don't use --touch-devices, mouse clicks work fine across both displays.
